Rethinking climate regulation from the ground up
It can be stomach-turning, watching the Trump administration torch federal climate policy. But what if some of what's burning wasn't working particularly well to begin with? Hannah Safford and Loren Schulman of the Federation of American Scientists' Center for Regulatory Ingenuity make the case, not for defending or trying to rebuild the status quo regulatory regime, but for imagining something better.

Using more of the grid we’ve already built
The US power grid runs at about 50% capacity on average — built for its worst day, underutilized every other day. As demand surges from data centers and electrification, utilities are racing to build more infrastructure. But Ian Magruder, who heads the new industry-backed Utilize Coalition, argues there's a cheaper, faster path: better use what we've already built — it will enable faster growth and bring down ratepayer bills, potentially by billions.

Should we block some sunlight to cool the planet?
In this episode, Dakota Gruener of Reflective walks me through her organization's new project, which maps the gaps in our scientific understanding of stratospheric aerosol injection — currently the leading candidate for directly cooling the planet. We get into what we don't know (including a factor-of-two disagreement on basic aerosol physics), who's already doing this without oversight, and the unsettling governance question of who controls the Earth's thermostat once humanity has grabbed it.

For data centers, a little flexibility goes a long way
The explosive energy demand from data centers is breaking our grid, pushing desperate developers to build their own on-site gas plants just to get online. To figure out how we avoid locking in decades of new fossil fuels, I’m joined by Camus CEO Astrid Atkinson and Princeton’s Jesse Jenkins to break down their proposed alternative. We dig into how adopting flexible grid interconnections and clean, battery-backed “power parks” can meet this massive load growth without abandoning our decarbonization goals.

The high-stakes battle over energy affordability in New York
New York Governor Kathy Hochul is trying to delay or roll back the state’s landmark climate law in the name of affordability. I’m joined by activist Pete Sikora to discuss the governor’s claims, what would actually serve affordability, and the larger politics behind this puzzling own-goal of a fight.

A Tesla vet tries to master the VPP market
In this episode, I’m joined by Kunal Girotra, who helped start and run Tesla’s residential energy business before leaving to start his own company. With Lunar, he has tried to create the most consumer-friendly possible battery and software ecosystem, which can seamlessly plug into solar panels, other devices, or VPPs. We talk about lessons learned and the future of residential electrification. This is a public episode.

How to design a brand-new city
I’m back with part two of my conversation with Jan Sramek, founder of California Forever, about his plan to build a brand-new city in Solano County. We get into the nuts and bolts of the urban design, discuss affordability and sustainability, get into governance issues, and look forward to what might happen next. This is a public episode.

Is the brand new city in California for real?
In this episode, I’m joined by Jan Sramek to discuss California Forever, the much-debated proposal to build a brand-new, sustainably designed city in Northern California. We explore the urbanist vision at the heart of the project, including a street grid inspired by Barcelona superblocks, and address the elephant in the room — the stealthy land acquisitions and the billionaire backers. Is this an urbanist utopia in the making or a grandiose con job? This is a public episode.

The fate of fossil fuel systems in the "mid-transition"
If the world takes its climate targets seriously, the coming decades will see fossil fuel systems shrinking as clean energy systems grow. In this episode, I talk with associate professor Emily Grubert about the issues that may arise during this “mid-transition” period. She has fascinating new study on the physical and financial cliffs that fossil fuel systems may go over as they decline and reach their “minimum viable scale” — and argues that public ownership of these dying industries might be the only way to gracefully phase them out.

Volts/Catalyst pod crossover: the biggest questions in clean energy
In this episode, I chat with Catalyst host Shayle Kann about the most pressing unresolved questions in the clean energy world today. We explore whether data center gigantism will break the grid, if the smart home revolution is destined for platform enshittification, whether billionaires should start testing solar geoengineering, and more.

What is PJM and why is everyone so mad about it?
PJM is the largest wholesale power market and transmission planning region in the US. Currently, it is stuck between a rock and a hard place: on one side, rising demand from data centers; on the other, a choked and congested interconnection queue that can’t keep pace. The result: rising prices and political discontent. I talk with Clara Summers of the Citizens Utility Board about how PJM can solve this dilemma and get prices under control.

Can fake meat help solve climate change?
Meat is responsible for roughly a fifth of climate change, the lion’s share of deforestation, 70% of our antibiotic use, and quite possibly the next pandemic — and consumption is going up every single year, with no end in sight. In this episode, Bruce Friedrich of the Good Food Institute joins me to argue that the only way out of this mess is better meat: plant-based and cultivated alternatives that can compete on price and taste, the way renewables now compete with fossil fuels.

Are utilities making too much money?
Utilities and their regulators are often protected by a "force field of tedium," but in this episode, I pierce the veil to discuss the complex machinery of utility profit-making. I’m joined by Joe Daniel of RMI to unpack the critical distinction between "return on equity" and "cost of equity," and why the former is almost always higher than necessary. We discuss how regulators can close this gap to lower consumer costs without hindering essential grid upgrades. This is a public episode.
